You control enchanted Equipment.

Enchant creature
At the beginning of the upkeep of enchanted creature's controller, Betrayer's Mantle deals 3 damage to that player.

Enchant two nonland permanents you control
Once each turn, when you activate an ability of one of the enchanted permanents, you may put a +1/+1 counter, a loyalty counter, or a charge counter on each enchanted permanent. (They can be different counters.)

Return up to two target creature cards with mana value X or less from your graveyard to the battlefield. They can't block this turn.

Tap up to two target creatures. Those creatures don't untap during their controller's next untap step.

Your opponents can't cast spells that share a card type with the exiled card during postcombat main phases.

As an additional cost to cast this spell, remove X +1/+1 counters from among creatures you control.
Create X 2/2 green Wolf creature tokens.

When Beyond the Veil enters, if it was cast, another target nonland permanent phases out. (Treat it and anything attached to it as though they don't exist.)
Nonland permanents you don't control with mana value 3 or less can't phase in.

Target creature you control becomes a copy of another target creature you control until end of turn.
Showcase {2}{U}{U} (Then if you cast this for its showcase cost, create a 1/1 red Bard creature token that can't block and exile this. Whenever it attacks, you may cast a free copy of this.)

Create two tapped colorless land tokens named Far-Off Lands with “{T}: Add one mana of any color.” (Then exile this card. You may cast the creature later from exile.)

Look at the top ten cards of your library. Put any number of legendary permanents with total mana value 6 or less from among them onto the battlefield. Put the rest on the bottom of your library in a random order.
For each planeswalker you control, you may activate one of their loyalty abilities. (You still pay its costs.)

Enchant creature

Enchanted creature has trample.

When Big Rock enters, it deals 2 damage to any target.

{T}, Sacrifice Big Rock: It deals 2 damage to any target. Activate this ability only if you control a Giant.

Pressure {2}{G} (You may cast this spell for its pressure cost if seven or more cards are in your graveyard.)
As an additional cost to cast this spell, sacrifice a creature.
Search your library for a creature card with mana value X or less, where X is equal to twice the sacrificed creature's mana value, put it onto the battlefield, then shuffle.
